Blackburn Mammoth 2Stage

2 / 8

The Blackburn Mammoth 2Stage has two settings (high pressure and high volume), which makes inflating mountain bike tires a snap. Start the inflation process in the high-volume setting, and then switch to high-pressure to top off at the end. The oversize aluminum barrel offers plenty of durability. A special grip-head mechanism keeps the pump firmly locked to the valve. The $30 pump weighs 168 grams, is compatible with presta or Schrader valves, and will fill a tire to 120 psi.
